Novel bile duct repair for bleeding biliary anastomotic varices: case report and literature review.

An unusual case of variceal bleeding at the site of a biliary enteric anastomosis is presented. This entity can occur when a high-to-low pressure gradient forms in a variceal field. In this case the anastomotic site was the location of the pressure gradient from the high-pressure small bowel varices to the low-pressure biliary tract. This was successfully treated by disconnection of the anastomosis. The resulting biliary defect was patched with small intestinal submucosa, which functioned successfully as a scaffold for biliary epithelial ingrowth.
